With this ansatz, no non-trivial reality conditions have to be solved, and the Hamiltonian constraint, though non-polynomial, can be quantized rigorously in a lattice regularization.4 pages, LaTeX, uses sprocl.sty; to appear in the Proceedings of the 2nd International Sakharov Conference on Physics, Moscow, May 20-24, 1996General Relativity and Quantum Cosmologytext
